Sefer Chasidim & the Rhineland Pietistsספר חסידים

The Chasidei Ashkenaz (Judah the Pious, Eleazar of Worms): penitential rigor, prayer-mysticism counting every word and letter of the liturgy as calibrated cargo, the Kavod (divine Glory) theology, and careful custody of the old Merkavah and name-lore — including golem traditions. The German tributary that flowed into the Kabbalah alongside the Provençal spring.
